AI Technical Summary
Existing underwater image color correction methods can only correct color shifts in certain specific scenes and cannot adapt to diverse underwater color shift situations, resulting in color errors still existing in the restored scene.
A two-stage adaptive method based on channel compensation is adopted, including an adaptive channel compensation stage and an automatic color equalization stage. Color compensation and adjustment are performed by calculating the bright channel matrix and pixel distance weighting. Combining the ideas of grayscale world and perfect reflection, an improved automatic color equalization algorithm is used to further restore true color and sharpness.
It significantly improves the generalization ability of underwater image color correction, making it applicable to a variety of underwater scenarios, effectively correcting color cast and improving image clarity.
